      Distribute an audio signal across two channels with a choice of methods.

        <h2>Initialization</h2>
        <p>
      <span class="emphasis"><em>imode</em></span> (optional) -- mode of the stereo
      positioning algorithm. 0 signifies equal power (harmonic)
      panning, 1 means the square root method, 2 means simple linear
      and 3 means an alternative equal-power pan (based on an UDO). The default value is 0.

        <p>
      <span class="emphasis"><em>pan2</em></span> takes an input
      signal <span class="emphasis"><em>asig</em></span> and distributes it across two
      outputs (essentially stereo speakers) according to the
      control <span class="emphasis"><em>xp</em></span> which can be k- or a-rate.  A
      zero value for <span class="emphasis"><em>xp</em></span> indicates hard left, and
      a 1 is hard right.
